1 D-Bus Python Bindings 0.83.1 (2010-02-18)
2 =========================================
6 * fd.o #21172: avoid some deprecation warnings in Python 2.6
8 * fd.o #15013: add dbus.lowlevel.MESSAGE_TYPE_SIGNAL etc., for those who care
9 about message types at a low level
11 * When removing signal matches, clean up internal state, avoiding a memory
12 leak in long-lived Python processes that connect to signals from arbitrarily
13 many object paths (fd.o #17551, thanks to Marco Pesenti Gritti)
15 * When setting the sender of a message, allow it to be org.freedesktop.DBus
16 so you can implement a D-Bus daemon in pure Python (patch from Huang Peng)
18 D-Bus Python Bindings 0.83.0 (2008-07-23)
19 =========================================
23 * Add bindings for DBusServer (thanks to Mathias Hasselmann, Huang Peng;
26 * Omit the service's traceback from certain D-Bus errors: specifically, those
27 that were probably deliberately raised as part of an API. Subclasses
28 of DBusException that indicate programmer error can turn the traceback
29 back on if it seems likely to be useful.
33 * Don't emit spurious Error messages if libdbus gives object-path handlers
34 a message that isn't a method call (most likely because of binding to a
35 locally emitted signal, as in fd.o #14199).
37 * Make multiple filters added by Connection.add_message_filter work
38 (fd.o #15547, thanks to Huang Peng).
40 * Make the API docs build correctly when out-of-tree
42 * Require dbus 1.0 so we can get rid of DBUS_API_SUBJECT_TO_CHANGE
44 D-Bus Python Bindings 0.82.4 (2007-12-10)
45 =========================================
49 * supplying reply_handler but not error_handler raises
50 MissingReplyHandlerException instead of MissingErrorHandlerException,
51 and vice versa (fd.o #12304, patch from René Neumann)
52 * Using non-recursive make for dbus/ directory should fix builds in some
53 environments (fd.o #12741)
57 * Everything is now under the same MIT/X11 license used for Collabora code in
59 * Added copyright headers to some files that were still missing them
61 D-Bus Python Bindings 0.82.3 (2007-09-27)
62 =========================================
66 * Out-of-tree builds with an absolute $(srcdir) can now build docs and run tests
67 * Closing private dbus.Bus no longer raises KeyError (fd.o #12096)
68 * async_err_cb(MyException()) now works (fd.o #12403)
69 * dbus.service.Object.remove_from_connection no longer claims that multiple
70 exports aren't possible (fd.o #12432)
71 * Setting _dbus_error_name as a class attribute of DBusException subclasses
76 * dbus.Bus(private=True) (use dbus.bus.BusConnection in new code, dbus.Bus
77 basically just adds the shared-connection behaviour)
81 * Code for which Collabora is the only copyright holder is now under the
82 same permissive MIT/X11 license under which dbus core is being relicensed
83 (this allows everything the old license would have allowed, and more)
85 D-Bus Python Bindings 0.82.2 (2007-08-01)
86 =========================================
88 Incompatibility with 0.82.1:
90 * If you pass the timeout argument to call_async or an asynchronous proxy
91 method call and expect it to be in milliseconds, you should change the
92 argument to be in seconds, and require dbus-python >= 0.82.2.
94 This feature didn't work at all in versions prior to 0.82.1, so any code
95 that works with 0.82.0 or earlier is unaffected.
99 * @dbus.service.method supports a rel_path_keyword argument for the benefit
100 of fallback objects, which provides the method implementation with the path
101 of the object within the exported subtree. For instance, if you have a
102 fallback object exported at /Fallback, and you call a method that has
103 rel_path_keyword='rel_path' on /Fallback and on /Fallback/Some/Where, the
104 method implementation will be called with rel_path='/' and with
105 rel_path='/Some/Where' respectively. (fd.o #11623)
107 * If you have epydoc version 3 (currently in beta), API documention is now
108 generated by default.
112 * As mentioned under "Incompatibilities" above, Connection.call_async()
113 measures timeouts in seconds, as was always intended.
114 This means that calls through a proxy object with a reply_handler and
115 error_handler will measure the timeout in seconds too.
117 * Introspect() now works on objects exported in more than one location.
120 * Building against Python 2.4 on non-Debian-derived distributions, or a
121 non-default Python version on Gentoo, should work again (revenge
122 of fd.o #11282, thanks Eyal Ben David).
124 D-Bus Python Bindings 0.82.1 (2007-07-11)
125 =========================================
127 The "double precision" release.
131 * Parse the timeout correctly in send_message_with_reply() and
132 send_message_with_reply_and_block(), fixing the use of non-default timeouts
134 * The tutorial no longer uses interactive-Python syntax, as it confused users.
136 * When making a call via a proxy object with ignore_reply=True, also get the
137 necessary introspection data asynchronously. This can avoid deadlocks in
138 some cases, such as calling methods in the same process (though this is not
139 recommended, for efficiency and sanity reasons).
140 * dbus.lowlevel exposes enough constants to write correct filter functions.
141 * We don't use dbus_watch_get_fd() (deprecated in libdbus) unless our libdbus
142 is too old to have the modern replacement, dbus_watch_get_unix_fd().
146 * Omitting the bus argument in the BusName constructor is deprecated.
147 The fact that it uses the globally shared connection to the session bus by
148 default is uncomfortably subtle.
150 D-Bus Python Bindings 0.82.0 (2007-06-19)
151 =========================================
155 * dbus.service.Object can start off with no Connection or object path, and
156 become exported later. If suitable class attributes are set, objects can
157 even be exported on multiple connections, or with multiple object-paths,
160 * dbus.service.FallbackObject implements a whole subtree of object-path space
163 * ``@method`` accepts a parameter ``connection_keyword`` so methods can find
164 out which connection to use for any follow-up actions.
166 * ``@signal`` has a new parameter ``rel_path_keyword`` which gets the path at
167 which to emit the signal, relative to the path of the FallbackObject.
168 ``path_keyword`` is now deprecated, and will raise an exception if used
169 on an object with ``SUPPORTS_MULTIPLE_OBJECT_PATHS``, including any
174 * In watch_name_owner, only the desired name is watched!
176 * When cleaning up signal matches, errors are ignored. This avoids using up
177 scarce pending-call allowance on dbus-daemon < 1.1, and emitting error
178 messages if we get disconnected.
180 * Signal handlers which are bound to a unique name are automatically
181 disconnected when the unique name goes away, reducing the likelihood that
182 applications will leak signal matches.
184 * Some corrections were made to the tutorial (@service and @method take a
185 parameter dbus_interface, not just interface; fd.o #11209).
187 * ${PYTHON}-config is used to get the Python include path (patch from
188 Sebastien Bacher/Ubuntu, fd.o #11282).
190 D-Bus Python Bindings 0.81.1 (4 June 2007)
191 ==========================================
195 * When an Error message on the bus is represented as a DBusException, the
196 error name is copied into the exception and can be retrieved by
197 get_dbus_name(). Exception handlers should use this instead of looking at
198 the stringified form of the exception, unless backwards compatibility
200 * DBusException objects now get all arguments from the Error message, not
201 just the first (although there will usually only be one). Use the 'args'
202 attribute if you need to retrieve them.
203 * The Connection, BusConnection and Bus classes have a method
204 list_exported_child_objects(path: str) -> list of str, which wraps
205 dbus_connection_list_registered()
206 * You can remove objects from D-Bus before they become unreferenced, by
207 using dbus.service.Object.remove_from_connection()
208 (https://bugs.freedesktop.org/show_bug.cgi?id=10457)
212 * Don't deadlock when removing a signal match that tracks name-owner changes.
213 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=426412)
214 * Include child nodes in introspection using list_exported_child_objects()
216 D-Bus Python Bindings 0.81.0 (9 May 2007)
217 =========================================
219 The 'series of tubes' release
220 -----------------------------
222 This is a feature release with support for non-bus-daemon connections
223 and improved GObject integration.
227 * Bus has a superclass dbus.bus.BusConnection (a connection to a bus daemon,
228 but without the shared-connection semantics or any deprecated API)
229 for the benefit of those wanting to subclass bus daemon connections
231 * BusConnection has a superclass dbus.connection.Connection (a
232 connection without a bus daemon) for use in peer-to-peer situations,
233 or distributed pseudo-bus situations without a bus daemon such as
234 Telepathy's Tubes API
236 * dbus.gobject_service.ExportedGObject is like dbus.service.Object, but
237 is also a subclass of GObject (with the necessary metaclass magic to
238 make this work). Until someone has verified that the GObject side of
239 things works as expected too, I consider this API to be potentially
242 * Connection and BusConnection have gained a number of useful methods,
243 including watch_name_owner (track name owner changes asynchronously,
244 avoiding race conditions), call_blocking and call_async (blocking and
245 asynchronous method calls without going via a proxy - note that these
246 are semi-low-level interfaces which don't do introspection), and
247 list_names, list_activatable_names and get_name_owner which are
248 simple wrappers for the corresponding org.freedesktop.DBus methods
250 * dbus.Interface (now also available at dbus.proxies.Interface)
251 and dbus.proxies.ProxyObject now have some reasonably obvious properties.
255 * All keyword arguments called named_service are deprecated in favour of an
256 argument called bus_name (to be compatible with both older and newer
257 dbus-python, you should pass these positional arguments).
259 * The bus keyword argument to dbus.proxies.ProxyObject is deprecated in
260 favour of an argument called conn, because proxies will work on non-bus
261 connections now (again, for maximum compatibility you should use a
262 positional argument for this).
264 * No warning is raised for this, but I consider calling any remote method
265 on a ProxyObject or Interface whose name is either alllowercase or
266 lower_case_with_underscores to be deprecated, and reserve the right
267 to add properties or methods of this form in future releases - use
268 ProxyObject.get_dbus_method if you must call a remote method named in
269 this way. Methods named following TheUsualDBusConvention or
270 theJavaConvention are safe.
274 * Exceptions in signal handlers print a stack trace to stderr (this can
275 be redirected elsewhere with Python's logging framework). Partially
276 addresses fd.o #9980.
278 * The reserved local interface and object path are properly checked for.
280 * When you return a tuple that is not a Struct from a method with no
281 out_signature, it's interpreted as multiple return values, not a
282 single Struct (closes fd.o #10174).
284 * If send_with_reply() returns TRUE but with pending call NULL, dbus-python
285 no longer crashes. This can happen when unexpectedly disconnected.
287 * Arguments are not examined for functions declared METH_NOARGS (this is
288 unnecessary and can cause a crash).
290 Other notable changes:
292 * dbus-python uses the standard Python logging framework throughout.
293 The first time a WARNING or ERROR is generated, it will configure the
294 logging framework to output to stderr, unless you have already
295 configured logging in your application.
297 * The tutorial now advocates the use of add_signal_receiver if all you
298 want to do is listen for signals: this avoids undesired activation,
299 e.g. of Listen or Rhythmbox (!). Addresses fd.o #10743, fd.o #10568.
